Product Introduction
BECTRON® PU 4528 / PH 4915 is a transparent polyurethane-based potting compound developed for applications where visibility of embedded components is essential. This two-component system, with a viscosity of 4000 mPas and a Shore A20 hardness, cures to a soft and flexible finish, making it especially suited for sensitive electronics. With a pot life of 25 minutes at 23 °C and a maximum operating temperature of +120 °C, it provides reliable thermal and mechanical stability. The formulation is UV-stable and non-yellowing under daylight conditions, making it ideal for use in environments where long-term clarity and weather resistance are required.
BECTRON® PU 4528 / PH 4915 Features
- Transparent yellow formulation ensuring visibility of potted components
- UV-stable and non-yellowing under sunlight exposure
- Soft, flexible cured state (Shore A20) for delicate component protection
- High viscosity (4000 mPas) for controlled application
- Solvent-free system with no bleeding at elevated temperatures
- Thermal stability up to +120 °C for demanding environments
BECTRON® PU 4528 / PH 4915 Applications
- Optoelectronic device encapsulation requiring soft protection
- Sensor potting in automotive or industrial electronics
- LED modules where optical clarity and UV stability are critical
- Applications involving exposure to light and heat without compromising material transparency
